How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a standard JSON-RPC response object containing a result field with the on-chain data requested (e.g. block object, hex-encoded balance, contract return value, transaction receipt) or an error object if the method or parameters were invalid.
Example use cases
Check wallet balance on Metis
“What's the current METIS token balance for wallet address 0xAbC...123 on the Metis network?”
Read smart contract state on Metis
“Call the totalSupply function on the Metis smart contract at 0xDef...456 — what does it return?”
Fetch recent transaction details
“Look up the details for transaction hash 0x789...abc on the Metis blockchain — was it successful and how much gas did it use?”

Choose this endpoint when you need pay-per-call access to Metis blockchain RPC without committing to a subscription-based node provider. It is well-suited for agents that need occasional or low-volume Metis RPC calls billed via USDC microtransactions through the x402 protocol, avoiding the overhead of managing your own node or API key.
Side effects
- Invalid JSON-RPC method name returns an error response
- Malformed params array causes parsing failure
- Unsupported Metis-specific method returns method not found error
- Payment failure (x402) blocks the request before it reaches the RPC node
- Node unavailability or network congestion may cause timeouts
- Requests to non-existent blocks or transactions return null results
